[Asterisk-Users] Txgain & Rxgain

[Humberto Aicardi]

Hi,

    I currently have  a TE210P with 2 E1 lines, one of them goes to the 
Telco which is fine and the other one goes to a Siemens HiPath 3750 PBX. 
The problem is that signal that the HiPath return is to HIGH and 
generates a lot of echo even when talking with a PAP2 on the same 
subnet, although when using the PAP2 to dial to a PSTN works fine. Well, 
doing some testing I found that setting RXGAIN=-12 and TXGAIN=-6 I 
eliminate the echo problems between the HIPATH and my SIP phones, but 
now the calls made to the PSTN are very low, is there a way to set RX & 
TX gains diferently on each TE210P E1?

Regards,
Humberto
